This patch adds platform side support code for the EP93xx SPI driver. This includes clock, resources and muxing. There is a new function: ep93xx_register_spi() which can be used by board support code to register new SPI devices for the board. This patch depends on patch 5998/1 ep93xx: added chip revision reading function Cc: Ryan Mallon <ryan@bluewatersys.com> Cc: David Brownell <dbrownell@users.sourceforge.net> Cc: Grant Likely <grant.likely@secretlab.ca> Signed-off-by: Mika Westerberg <mika.westerberg@iki.fi> Acked-by: H Hartley Sweeten <hsweeten@visionengravers.com> Acked-by: Martin Guy <martinwguy@gmail.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
